I got an Acer Aspire 3 15 laptop for Christmas so it's had very little use, but it keeps dropping the wifi signal after about an hour. When I try to re-connect it says the signal is weak, but my Toshiba laptop beside it says the signal is strong and stays connected. I can place the Acer right beside the router ( I'm on Starlink satellite for Wifi) but it fails to connect. If I unplug the router and reboot the computer at the same time, I'll get back on for another hour but I have 3 other computers staying connected just fine. The trouble shooter keeps telling me "default gateway not available". I phoned Acer last night and started a Case file … he got me to do a total system reboot which I finished up reloading the personal info to run Windows 11 this morning, but after an hour I got the boot again. I did manage to run Windows update and install all the latest drivers but that's not cutting it. The IT tech said we'd have to hard wire into the LAN connection to do any more, but the router uses the big square plugs and the biggest one on this skinny little laptop is a USB. I've barely had this laptop a month and it's already cost me more time than it's worth…. any ideas short of a stick of dynamite?
